The device comprises a base plate, a carrying guide rail, a carrying sliding block, a fixed base plate, a drilling assembly, a carrying sliding block, a movable base plate, an angle positioning assembly, a hoisting plate, a step driving assembly and a heating assembly. The carrying sliding block is connected with the carrying guide rail in a sliding mode. The fixed base plate is arranged at the top end of one group of carrying sliding blocks. The drilling assembly is arranged at the top end of the fixed base plate. The movable base plate is arranged at the top end of the other group of carrying sliding blocks. The angle positioning assembly is arranged at the top end of the movable base plate. The step driving assembly is arranged at the top end of the hoisting plate. The heating assembly is arranged on the base plate. The clamping spring starts to pull the two clamping blocks. The telescopic block in the middle of the clamping block is passively retracted. The bent buckle and the slope lock the fixed side wall. High-frequency alternating current is supplied to the electrode wire. The spiral wire heats the metal bone nail. This not only softens the metal for subsequent processing, but also increases the service life of the device.
